Scheme and the present invention will be described in detail in conjunction with embodiment.
According to an aspect of the present invention, a kind of busbar connector connection structure is provided, wherein the busbar connector connection structure packet
Include the first busbar connector 10 being disposed adjacent and the second busbar connector 20 and electrical connection first busbar connector 10 and the second busbar connector
20 interconnecting piece 30, the interconnecting piece 30 connect with first busbar connector 10 and the second busbar connector 20 in identical level height
It connects, the interconnecting piece 30 is flexible piece and extends in the horizontal plane where the level height.
The present invention also provides a kind of mould groups, wherein the mould group includes the first battery core 40, the second battery core 50 and of the invention
Busbar connector connection structure, first busbar connector 10 are connected to first battery core 40, and second busbar connector 20 is connected to institute
State the second battery core 50.
Wherein, the first busbar connector 10 is connected to the pole (the first pole 41) of (such as welding) the first battery core 40, and second converges
Stream row 20 is connected to the pole (the second pole 51) of (such as welding) the second battery core 50.
The present invention also provides a kind of battery packs, wherein the battery pack includes mould group of the invention.
The present invention also provides a kind of vehicles, wherein the vehicle includes battery pack of the invention.The battery pack can be made
For the power battery pack of vehicle.It is buffering battery core because shaking influencing each other between battery core, Ke Yi caused by vehicle movement
Battery core is set between adjacent battery core and buffers cotton 60.
In busbar connector connection structure of the invention, interconnecting piece 30 is flexible piece, adapt to the when can expand, shrink in battery core
The distance between one busbar connector 10 and the second busbar connector 20 change and stretch, and avoid applying shearing force to battery core.In addition, interconnecting piece
30 extend in the horizontal plane, take full advantage of the space between the first busbar connector 10 and the second busbar connector 20, and are not take up additional
Space, be conducive to mould group, the compact design of battery pack, suitable for the vehicle demand more demanding to this.
Wherein, interconnecting piece 30 can be various appropriate forms, as long as can be conductive and having flexibility in the first busbar connector
10 and when the second the distance between busbar connector 20 variation accordingly stretch.Exceptional space is occupied to reduce, as shown in Figure 1, institute
Stating interconnecting piece 30 includes the flexible tape part extended in the horizontal plane.Using flexible tape part, its thickness can be ignored substantially
Degree, as the linear extended in the horizontal plane.
In addition, to be flexible convenient for flexible tape part, it is preferable that the flexible tape part can have bending shape, flexible
The length of part between two positions of strap-like member connecting with the first busbar connector 10 and the second busbar connector 20 is greater than this two
The distance between position, when becoming larger so as to the distance between the first busbar connector 10 and the second busbar connector 20 (battery core contraction)
So that bending is the partially unfolded, extended with adaptability.When the distance between the first busbar connector 10 and the second busbar connector 20 become smaller (electricity
Core expansion) when, flexible tape part can be close to each other in the part of the two sides of bending place, is shunk with adaptability.
